Arianespace's Ariane 5 orbits Galaxy 30, MEV-2 and BSAT-4b


The Ariane 5 for Arianespace's Flight VA253 was equipped with a new vehicle equipment bay that enabled the launcher's payload capacity to be increased.

Ariane 5 flexed its heavy-lift muscles on Arianespace's latest launch from the Spaceport in French Guiana, successfully placing the triple payload of Galaxy 30 (G-30), the Mission Extension Vehicle-2 (MEV-2) and BSAT-4b into geostationary transfer orbit.

Designated Flight VA253 in Arianespace's numbering system, today's mission was performed from the Spaceport's ELA-3 launch zone – with Ariane 5 deploying its three passengers during a sequence lasting 47 minutes from liftoff to final separation. It marked the 253rd launch of an Ariane-series vehicle to date, and the 109th using an Ariane 5.

Today's mission utilized an Ariane 5 ECA version with increased payload capacity through the introduction of a new vehicle equipment bay for the launch vehicle. Since kicking off a continuous improvement program for Ariane 5 in 2016, prime contractor ArianeGroup has increased the launcher's payload capacity by 300 kg. for the benefit of Arianespace. This raises the total mass of payload passengers that can be carried by Ariane 5 to 10,200 kg.; for today's mission, the combined mass of G30, MEV-2 and BSAT-4b was 9,703 kg.
"Flight VA253 marked another mission of innovation for us," said Stéphane Israël, the Arianespace Chief Executive Officer. "This was the first time that we delivered three satellites to geostationary transfer orbit on a single launch, and it utilized the most capable Ariane 5 ever – with the increased payload capacity of 10.2 metric tons that is now available for satellite payloads."

Continued success with Intelsat and Northrop Grumman

Deployed first in the flight sequence 27 minutes after liftoff, G-30 is the 62nd satellite Arianespace has launched for operator Intelsat, continuing a business relationship that extends back to 1983. It was produced by Northrop Grumman based on its GEOStar-2 platform, and will provide UHD video distribution/broadcast and broadband services that cover North America.

G-30 was carried as Ariane 5's upper payload component, stacked with the MEV-2, built by Northrop Grumman's wholly-owned company SpaceLogistics LLC. MEV-2 is designed to dock with geostationary satellites whose fuel has nearly depleted, thereby extending their useful lifetimes.

MEV-2 will rendezvous and dock in early 2021 with the Intelsat 10-02 (IS 10-02) satellite, originally launched in 2004. The Mission Extension Vehicle is to utilize its own thrusters and fuel supply to control the IS 10-02 satellite's orbit.
Including G-30 and MEV-2, Arianespace has now orbited a total of 30 spacecraft produced by Northrop Grumman or its companies.

Another launch for Japan's B-SAT with a Maxar-built satellite

The lower passenger in Ariane 5's multi-payload configuration was BSAT-4b, which was orbited for the Japanese operator B-SAT. Produced by Maxar Technologies, it uses this manufacturer's popular 1300-class spacecraft bus for commercial communications satellites.
BSAT-4b is designed for Ultra-High-Definition (UHD, 4K and 8K) direct-to-home television broadcasting across Japan in conjunction with its twin, BSAT-4a – which was launched by an Ariane 5 in 2017. All of BSAT's 10 satellites have been orbited on Arianespace missions.

Ariane 5's launch by the numbers

Flight VA253 was Arianespace's fifth launch so far in 2020, and it follows two other heavy-lift Ariane 5 missions this year: the first orbited the EUTELSAT KONNECT and GSAT-30 satellites in January; while the second, performed in February, lofted JCSAT-17 and GEO-KOMPSAT-2B. Two medium-lift Soyuz missions also were conducted in February and March, with each successfully delivering 34 OneWeb constellation satellites to low Earth orbit.

The next mission in Arianespace's 2020 manifest is the proof of concept flight for Europe's Small Spacecraft Mission Service (SSMS) – which will deploy 46 small CubeSats and seven microsatellites from the light-lift Vega launcher, using a new-design rideshare dispenser system. This flight is planned for September 1.

Triple mission success for Ariane 5: the Galaxy 30, MEV-2 and BSAT-4b satellites reach geostationary transfer orbit



Arianespace's fifth successful mission of 2020 orbited two telecommunications satellites and one satellite servicing vehicle for operators Intelsat, B-SAT and Northrop Grumman.

With this launch for two of its most loyal customers, as well as a new operator, Arianespace demonstrates the reliability and competitiveness of its launch service solutions, as well as the excellence of its long-established customer relationships.

On Saturday, August 15 at 22:04 UTC, Ariane 5 Flight VA253 was successfully performed from the Guiana Space Center, orbiting two satellites produced by Northrop Grumman: Galaxy 30 for Intelsat, and MEV-2 for SpaceLogistics LLC, a 100% subsidiary of Northrop Grumman; along with BSAT-4b, built by Maxar Technologies for the Japanese operator B-SAT.

"Arianespace is delighted to have served two loyal customers – Intelsat and B-SAT – as well as Northrop Grumman's subsidiary, SpaceLogistics LLC," declared Stéphane Israël, the Chief Executive Officer of Arianespace. "As part of this mission, three satellites were deployed by the most powerful Ariane 5 ever launched, thus demonstrating the competitiveness of our launch solutions and our capability for continuous innovation."

The Galaxy 30 UHD video distribution/broadcast and broadband satellite, built for global network operator Intelsat, will cover North America.

BSAT-4b will be used for Ultra-High-Definition (UHD, 4K and 8K) direct-to-home television broadcasting across Japan, in conjunction with its twin, BSAT-4a, launched by Arianespace in 2017.

The Arianespace relationship with satellite operators Intelsat and B-SAT has continued for several decades, and has grown stronger over time. Since 1983 – the date of the first mission for Intelsat – Arianespace has launched 61 satellites on behalf of this global operator. For B-SAT, the Japanese operator has entrusted Arianespace with the launch of its entire fleet – a total of 10 satellites.

Flight VA253's third passenger, the Mission Extension Vehicle-2 (MEV-2), is a satellite servicing vehicle designed to dock with satellites in orbit. It will provide life extension services. MEV-2's first customer will be the Intelsat 10-02 satellite, which has been in service in geostationary orbit since 2004 and will have its operational life extended by five years.

The triple-payload launch performed with Flight VA253 to orbit two telecommunications satellites and a servicing spacecraft is a first for Ariane 5.

Another important point: Flight VA253 utilized the Ariane 5 heavy-lift launcher, developed and produced by ArianeGroup, which has increased its payload capacity by 85 kg. for this flight with the introduction of a new vehicle equipment bay (VEB) – bringing total capacity for the satellite payloads to 10,200 kg. on missions to geostationary transfer orbit (GTO).

This Ariane 5 launcher is thereby the most powerful ever operated by Arianespace, marking the culmination of the continuous improvement program for Ariane 5's performance and competitiveness that was implemented in 2016 by ArianeGroup for the benefit of Arianespace. It has provided a performance gain 300 kg., which continues to be available for customers on Ariane 5 missions planned until the end of the launcher's operation.

The Ariane 5 launcher is a joint European government-industry program. Arianespace is responsible for marketing and operating Ariane 5 launches from the Guiana Space Center in Kourou, French Guiana, with support from teams of the French space agency (CNES) and the European Space Agency (ESA) – which is responsible for the Ariane programs. All industrial activities relating to Ariane 5 are managed by ArianeGroup. This includes the equipment and structures, the manufacturing of engines, integration of the various stages, followed by integration of the complete launcher in French Guiana before its delivery to Arianespace for liftoff.

McLean, Va. – August 15, 2020 – Intelsat, operator of the world's largest integrated satellite and terrestrial network, announced the successful launch of Galaxy 30, a geosynchronous communications satellite that will primarily provide high-performance television distribution service to Intelsat's North American customers.

Northrop Grumman's Mission Extension Vehicle 2 (MEV-2) was part of the same successful launch today. The Intelsat 10-02 satellite is scheduled to be its first customer in early 2021.

The Northrop Grumman-manufactured Galaxy 30 and MEV-2 launched on the Arianespace Ariane 5 rocket from the Guiana Space Center near Kourou, French Guiana at 6:04 p.m. EDT. Galaxy 30 separated from the rocket at 6:31 p.m. EDT, and Intelsat confirmed its signal acquisition at 7:02 p.m. EDT.

Galaxy 30 is the first satellite in Intelsat's Galaxy fleet refresh plan and will replace Galaxy 14 at 125 degrees west once it is in service in early 2021. The Intelsat Galaxy fleet is the most reliable and efficient media content distribution system in North America, offering customers an unmatched penetration of cable head-ends.

"Today's launch of Galaxy 30 demonstrates Intelsat's long-term commitment to our North American media customers," said Intelsat CEO Stephen Spengler. "At Intelsat, we're constantly innovating, investing in and upgrading our satellite fleet and terrestrial infrastructure. Galaxy 30 is a great example of how we help our customers stay ahead of evolving consumer demands, today and well into the future."

With C-, Ku-, Ka- and L-band capabilities, Galaxy 30 is the first four-frequency Intelsat satellite. In addition to serving Intelsat's media business customers, Galaxy 30 will also offer broadband, mobility and network services to Intelsat mobile network operator, enterprise and government customers in North America. The new satellite is also carrying a U.S. Federal Aviation Administration hosted payload for Leidos.

Galaxy 30 will play an important role in Intelsat's U.S. C-band spectrum transition plan, which is accelerating America's path to 5G. Intelsat is facilitating the work of the U.S. Federal Communications Commission (FCC) in transitioning and safeguarding media services currently utilizing the lower portion of the band to make way for 5G wireless services. Intelsat is not seeking any reimbursement costs from the FCC's public auction proceeds for any aspect of the Galaxy 30 launch or relocation.

"Today's launch was especially important for Intelsat because Northrop Grumman's innovative MEV-2 launched alongside Galaxy 30," continued Spengler "Intelsat was proud to partner with Northrop Grumman earlier this year to pioneer the future of in-space servicing with MEV-1 and our Intelsat 901 satellite. We're looking forward to this next exciting servicing mission with Intelsat 10-02."

MEV-2 is scheduled to dock with Intelsat 10-02 in 2021, providing it with five additional years of high-performance life. Intelsat 10-02 delivers media distribution and broadband services to Intelsat customers across Europe, the Middle East, Africa and South America. Telenor Satellite contracts for capacity on Intelsat 10-02 and is partnering with Intelsat to bring the benefits of in-space servicing to its customers.

ЦитироватьФранцузская ракета Ariane 5 вывела на орбиту три космических аппарата
16.08.2020 7:03:10
       Париж. 16 августа. ИНТЕРФАКС - Тяжелая ракета-носитель Ariane 5 Европейского космического агентства (ЕSА), стартовавшая с космодрома Куру во Французской Гвиане, вывела на орбиту три космических аппарата, сообщила компания-оператор Arianespace.
      "Миссия VA253 успешно осуществлена", - говорится в сообщении.
       Ракета-носитель вывела на геостационарную орбиту аппарат MEV-2 (Mission Extension Vehicle) американской корпорации Northrop Grumman, предназначенный для продления сроков эксплуатации спутников. Он должен состыковаться со спутником связи Intelsat 10-02, который уже почти исчерпал свои запасы топлива для поддержания ориентации, и "дозаправить" его.
       На орбиту также выведен спутник Galaxy 30 компании Intelsat для расширения высокочастотного телевизионного покрытия территории США. На нем, кроме того, размещено оборудование Федеральной авиационной администрации США, предназначенное для совершенствования технического обслуживания полетов гражданской авиации.
       Третьим спутником является японским телекоммуникационным аппаратом BSAT-4b. Созданный компанией Maxar, он будет использоваться для телевизионного вещания в формате сверхвысокой четкости (4K и 8K) в Японии.
